What is an MPRN?

MPRN stands for Meter Point Reference Number. It is the ID that the gas industry uses to pinpoint the exact supply point for a building. If you are getting your head around the wider basics of business gas, this overview of business gas gives the bigger picture around supply, contracts, and switching.

The easiest mental model is the VIN on a car. It is the identifier that sticks with the thing itself, not the bits you can swap out. Your MPRN stays tied to the property, even if the meter is replaced or you change supplier.

An MPRN is always numbers only. It is usually 6 to 10 digits long, and it never includes letters.

MPRN vs meter serial number

This is where people get tripped up. The meter serial number identifies the physical meter, which is the box on the wall. If that meter is exchanged, the serial number changes with it.

The MPRN identifies the supply point for the building. It stays the same even if the meter changes, and it is the number suppliers use to pull the right supply record.

If you see letters in the number you have found, it is a decent clue that you are looking at a meter serial number, not an MPRN.

Where to find your MPRN

Most of the time, your MPRN is on your gas bill. It is often on the second page, or in the supply details and charges breakdown.

You will not usually find it printed on the meter itself. That is annoying, but it is normal. The meter casing tends to show the serial number for the hardware.

If you do not have a bill yet, for example you have just moved in, you can use an online lookup tool to find the MPRN using the property address.

Pro Tip
When you find your MPRN, save it somewhere sensible. A note on your phone beats a frantic search five minutes before someone asks for it.

Why your MPRN matters for quotes

Suppliers use the MPRN to match your request to the correct supply record. Without it, they may have to rely on address matching, which can be slower and can cause mix-ups in multi-unit buildings.

If you are doing a business gas price comparison, having the MPRN upfront helps suppliers return accurate gas quotes for business. It also reduces the risk that a quote is based on the wrong site details.

This is one of those small admin details that has an outsized impact. The MPRN makes sure everyone is talking about the same supply point from the start.
